The LEE Filters Back Plate Cover consists of a pair of replacement fasteners that together with a corresponding LEE Filters Front Plate Cover, helps to securely attach compatible LEE Filters Filter Holder Guides to the Back Plate included with a LEE Filters Foundation Kit.

Filter Holder Guides from LEE Filters are made for 1mm, 2mm, or 4mm-thick filters and allow such filters that are 100mm wide to be used with the LEE Filters Foundation Kit. Those guides are attached by first placing the Back Plate Cover onto the Back Plate followed by the number of Filter Holder Guides to be used, the Front Plate Cover, and finally, a set of LEE Filters Guide Screws that is of the correct length to fasten those components to the Back Plate.
